《分析性寫作》，介紹言簡意賅： The Popular, brief rhetoric that treats writing as thinking, WRITING ANALYTICALLY, Sixth Edition, offers a series of prompts that lead you through the process of analysis and synthesis and help you to generate original and well-developed ideas. The book's overall point is that learning to write well means learning to use writing as a way of thinking well. To that end, the strategies of this book describe thinking skills that employ writing. As you will see, this book treats writing as a tool of thought--a means of undertaking sustained acts of inquiry and reflection.

Synopsys' widely-used design constraints format, known as SDC, describes the "design intent" and surrounding constraints for synthesis, clocking, timing, power, test and environmental and operating conditions. SDC has been in use and evolving for more than 20 years, making it the most Popular and proven format for describing design constraints. Essentially all synthesized designs use SDC and numerous EDA companies have translators that can read and process SDC.

Mobile wireless communications are in constant evolution due to the continu- ously increasing requirements and expectations of both users and operators. Mass multimedia* services have been for a long time expected to generate a large amount of data traffic in future wireless networks [1]. Mass multimedia services are, by definition, purposed for many people. In general, it can be distinguished between the distribution of any Popular content over a wide area and the distribu- tion of location-dependent information in highly populated areas. Representative examples include the delivery of live video streaming content (like sports compe- titions, concerts, or news) and file download (multimedia clips, digital newspa- pers, or software updates).

Nowadays sensors are part of everyday life in a wide variety of fields: scientific applications, medical instrumentation, industrial field, ...and, last but not least, Popular mass production and low-cost goods, like smartphones and other mobile devices. Markets and business behind the field of sensors are quite impressive. A common trend for consumer applications is miniaturization which requires, on one side, a lot of research, development efforts, and resources but, on the other hand, allows costs and final application size reduction. In this scenario scientific community and industries are very active to drive innovation.

This reference design describes the design of a 3-phase AC induction vector control drive with position encoder coupled to the motor shaft. It is based on Motorola’s DSP56F805 dedicated motor control device. AC induction motors, which contain a cage, are very Popular in variable speed drives. They are simple, rugged, inexpensive and available at all power ratings. Progress in the field of power electronics and microelectronics enables the application of induction motors for high-performance drives, where traditionally only DC motors were applied. Thanks to sophisticated control methods, AC induction drives offer the same control capabilities as high performance four-quadrant DC drives.

ABSTRACTThe flyback power stage is a Popular choice for single and multiple output dc-to-dc converters at powerlevels of 150 Watts or less. Without the output inductor required in buck derived topologies, such as theforward or push-pull converter, the component count and cost are reduced. This application note will reviewthe design procedure for the power stage and control electronics of a flyback converter. In these isolatedconverters, the error signal from the secondary still needs to cross the isolation boundary to achieveregulation. By using the UC3965 Precision Reference with Low Offset Error Amplifier on the secondaryside to drive an optocoupler and the UCC3809 Economy Primary Side Controller on the primary side, asimple and low cost 50 Watt isolated power supply is realized.

首先下載軟件，解壓軟件，安裝在程序中找到SEGGER,選里面的J-FLASH，進(jìn)入界面，剛開始的那個界面可以忽略，不用建project也可以；單擊菜單欄的“Options---Project settings”打開設(shè)置，進(jìn)行jlink配置;正在General選項，選擇“USB”，一般都是默認(rèn)配置，確認(rèn)一下即可;然后在CPU選項，選擇芯片型號，先選擇“Device”才能選擇芯片型號，芯片型號，要根據(jù)你使用的芯片進(jìn)行選擇;在Target interface選項 里面選擇SWD模式;首先Target里面選“Connection”連接目標(biāo)芯片，然后 Target--Auto進(jìn)行程序燒寫;首先Target里面選擇“Connection”連接目標(biāo)芯片，然后 Target--Auto進(jìn)行程序燒寫.SEGGER J-Links are the most widely used line of debug probes available today. They've proven their value for more than 10 years in embedded development. This Popularity stems from the unparalleled performance, extensive feature set, large number of supported CPUs, and compatibility with all Popular development environments.

本文主要介紹如何在Wado設(shè)計套件中進(jìn)行時序約束，原文出自 xilinx中文社區(qū)。1 Timing Constraints in Vivado-UCF to xdcVivado軟件相比于sE的一大轉(zhuǎn)變就是約束文件，5E軟件支持的是UcF（User Constraints file，而 Vivado軟件轉(zhuǎn)換到了XDc（Xilinx Design Constraints）。XDC主要基于SDc（Synopsys Design Constraints）標(biāo)準(zhǔn)，另外集成了Xinx的一些約束標(biāo)準(zhǔn)可以說這一轉(zhuǎn)變是xinx向業(yè)界標(biāo)準(zhǔn)的靠攏。Altera從 TimeQuest開始就一直使用SDc標(biāo)準(zhǔn)，這一改變，相信對于很多工程師來說是好事，兩個平臺之間的轉(zhuǎn)換會更加容易些。首先看一下業(yè)界標(biāo)準(zhǔn)SDc的原文介紹：Synopsys widely-used design constraints format, known as sDc, describes the design intent"and surrounding constraints for synthesis, clocking, timing, power, test and environmental and operating conditions. sDc has been in use and evolving for more than 20 years, making it the most Popular and proven format for describing design constraints.
